Five kilograms of continuous boron fibers are introduced in a unidirectional orientation into 8 kg of an aluminum matrix. The boron fibers have a density of 2.36 g/cm^3 and the aluminum has a density of 2.7 g/cm^3 . Calculate the following: a. The density of the composite.
b. The modulus of elasticity parallel to the fibers.
c. The modulus of elasticity perpendicular to the fibers.

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
